NetGuard - no-root firewall

Take control of your internet with NetGuard - no-root firewall, the most comprehensive mobile security app that blocks unwanted network access without requiring root permissions. Whether you're concerned about data usage, battery drain, or privacy, NetGuard gives you granular control over which apps can connect to Wi-Fi or mobile networks.

Managing your app permissions has never been simpler. Block entire applications or allow access only when your screen is on. Deny connections while roaming to avoid unexpected charges. You can even restrict system applications and individual addresses per app, giving you surgical precision over your device's network behavior. Best of all, this happens locally on your device—no servers involved, no data sent elsewhere, completely transparent.

Reduce data consumption and extend battery life by preventing background apps from consuming your connection. Your privacy stays protected because NetGuard doesn't track you, show ads, or phone home. The app is 100% open source, so you can audit exactly what it does. Active development means new features and security improvements arrive regularly, with support for Android 5.1 and later across IPv4/IPv6, TCP/UDP protocols, and even tethering scenarios.

The free version includes all essential features: simple controls, material design with light and dark themes, optional notifications when apps access the internet, and per-application network usage tracking. For power users, the Pro version unlocks advanced capabilities: complete traffic logging with search and filtering, detailed per-address allow/block rules, application notifications for new network activity, real-time network speed graphs in your status bar, and five additional premium themes.

Unlike other no-root firewalls, NetGuard combines ease of use with powerful advanced options, all without requiring dangerous system-level access. The app works by routing traffic through Android's VPN service, filtering connections on-device rather than relying on external servers. This approach protects your data while maintaining simplicity.

If you want maximum control over your privacy and data usage without complexity or compromise, NetGuard - no-root firewall is the solution you've been looking for. Download today and experience the freedom of network independence.
